Embodiment 1

[0026] Embodiment 1 White tea essential oil of the present invention and its preparation (1)

[0027] The large-leaf white tea in the Pu'er area of ​​Yunnan is used as the material.

[0028] Instrument: The main equipment is the extractor, which consists of Made of stainless steel tube, pressurized buffer and double-layer structure, the inner cylinder is made of stainless steel, and the outer cylinder is made of brass, which are closely matched with each other. Its equipment composition includes: CO 2 Steel cylinders, desiccators, condensate ice water baths, plunger pumps, pressurized buffer bottles, constant temperature baths, preheating tubes, extractors, ice water beakers, sediment separators, buffers, wet flow meters.

[0029] Specific steps are as follows:

[0030] From 6:00 to 9:00 in the morning, hand-picked young leaves of one heart and two leaves of similar size were spread neatly in a backlit room to a thickness of 3-5cm, the temperature was controlled at 35°C, a...

Embodiment 2

[0031] Embodiment 2 White tea essential oil of the present invention and its preparation (2)

[0032] Materials and instruments are the same as in Example 1.

[0033] Specific steps are as follows:

[0034] From 6:00 to 9:00 in the morning, hand-picked young leaves of one heart and two leaves of similar size were spread neatly in a backlit room to a thickness of 3-5cm, the temperature was controlled at 35°C, and the humidity was 55%-60%, withering until weight loss The rate is 55%-60%, and then placed in a dryer for 30 minutes at 110°C. Finally, crush the white tea leaves and pass through a 10-mesh sieve to obtain coarse powder, pack the weighed coarse tea powder in a gauze bag, put it into the extractor, and seal the top cover. Turn on the power to the bath. Open the valve of the carbon dioxide cylinder, let the gas pass through the dryer along the pipeline, cool the condenser (soaked in an ice-water bath), plunger pump, and enter the pressurized buffer bottle. After the ...

Embodiment 3

[0035] Embodiment 3 white tea essential oil of the present invention and its preparation (3)

[0036] Materials and instruments are the same as in Example 1.

[0037] Specific steps are as follows:

[0038] From 6:00 to 9:00 in the morning, hand-picked young leaves of one heart and two leaves of similar size were spread neatly in a backlit room to a thickness of 3-5cm, the temperature was controlled at 30°C, and the humidity was 50%-55%, withering until weight loss The rate is 50%-55%, and then placed in a dryer for 20 minutes at 120°C. Finally, crush the white tea leaves and pass through a 10-mesh sieve to obtain coarse powder, pack the weighed coarse tea powder in a gauze bag, put it into the extractor, and seal the top cover. Turn on the power to the bath. Open the valve of the carbon dioxide cylinder, let the gas pass through the dryer along the pipeline, cool the condenser (soaked in an ice-water bath), plunger pump, and enter the pressurized buffer bottle. After the ...

Abstract

The invention relates to white tea essential oil for treating tinea pedis and dandruff and application thereof. The white tea essential oil is prepared by the following method: collecting fresh white tea tender shoots, withering in a backlight room under the conditions that the temperature is 30-35 DEG C and the humidity is 50-60% until the weight loss rate is 40-60%, drying, and performing supercritical CO2 fluid extraction. The components of the obtained essential oil are further analyzed through GC-MS. Bacteriostatic tests prove that the white tea essential oil has an excellent inhibition effect on trichophyton rubrum and candida albicans causing tinea of feet and hands and malassezia causing dandruff, and animal experiments prove that the white tea essential oil has an excellent itching relieving effect. Therefore, the white tea essential oil disclosed by the invention can be used for preparing medicines or cosmetics for treating or relieving tinea of feet and hands and dandruff.

Description

technical field [0001] The present invention relates to the extraction of plant essential oil and its use, in particular to a white tea essential oil for treating athlete's foot and dandruff and its use. Background technique [0002] White tea is a special treasure among Chinese teas. It is a micro-fermented tea. Through special techniques, the leaves and buds of the white tea tree in the tea (Camelliasinensis (L.) O.Ktze.) are withered, baked (or dried in the shade), sorted, and compounded. fire, crafted. White tea essential oil is a volatile oil extracted from white tea leaves and buds. [0003] Journal paper (Yang Jing. Research on the aroma components of tea leaves extracted by supercritical fluid [J]. Food Science and Technology, 2008 (06): 83-85.) discloses the use of supercritical fluid extraction technology to extract the aroma components of tea leaves. pressure, time, CO 2 The influence of flow rate on the yield of supercritical fluid extraction, the general orth...
